Pyridine → HCID 53897384, compound

Participants

Reaction Steps

To a stirred solution of 45.0 g (0.347 mole) of methylsulfamoyl chloride (Example 2, pt. a) in 100 ml of methylene chloride was added in a thin stream a solution of 25.0 g (0.145 mole) of 2-(4-chlorophenoxy)ethanol (Lancaster Synthesis, Inc., Windham, N. H. 03087) in 30 ml (0.369 mole) of pyridine and 100 ml of methylene chloride and the reaction mixture was stirred at ambient temperature for 3 days. The solids were removed by filtration and the filtrate was evaporated under reduced pressure to yield a brown, viscous residue. The residue was partitioned between water and ethyl ether (400 ml each). The organic layer was washed twice with 300 ml portions of water, dried over magnesium sulfate and the solvent evaporated under reduced pressure to yield a solid residue. The solid was triturated with 100 ml of isopropyl ether and the solid was recollected by filtration. The solid was recrystallized from isopropyl ether to give 12.9 g (34%) of title compound as a white solid, mp 101°-104° C.
